  • C12H22O11 + H2O -> 4CH3CH2OH + 4CO2
  • 1000 g/342,3 g/Mol = 2,92141396 Mol
  • 4*2,92141396 Mol = 11,6856558 Mol
  • 46g/Mol*11,6856558 Mol = 537,540167 g.

  • 3H2 + N2 = 2NH3
  • m for H 12,5
  • m for N 25,3
  • M for H 2,02 g/mol
  • M for N 28,14 g/mol
  • n for H 6,25 mol
  • n for N 0,9 mol
  • 6,25/0,9 er ikke lig 3

  • MolH = 10g/2*1g/mol = 5 Mol.
  • MolCl = 10g/(35,5*2) = 0,14 Mol.
  • MolHCL = 0,14Mol*2 = 0,28 Mol.
  • GHCL = 0,28Mol*36,5g/Mol = 10,22 g.
